The important thing to note here is that none of the VZW LTE global Motorola devices has a SIM lock enabled and no unlock code is required nor will any purchased code work. They are all SIM unlocked by default and nobody should waste time and money purchasing a code.

The XT907 RAZR M has a different radio chipset and you can edit the NVM to disable the block on US GSM carriers without root or unlocking the bootloader, but all of them can be used with international GSM carriers without any modifications, except the Bionic which needs a different NV edit for the band configuration for GSM use.

Thanks I must have misread the post about the M needing to be unlocked and rooted...

Hey, Do you happen to have instructions or would like to help with adding the Tigo APN info on to the XT912. I went to Colombia and Tigo gave me a micro sim but I experienced the same issue you had, no data except calls and texts. I now want to send the phone to a family member there and want to make sure they can get data too...Any help will be appreciated

I had a XT912 in Colombia, I can talk and text but initially no data, I manually added the APN info (Tigo) and the now I have data but no Wifi Hotspot, so I install an apk called Wifi Tether from the Play Store. You need to be rooted and thats all. My Xt912 has data and share it via wifi.

Nobody that I am aware is actively working on this issue anymore. There is not likely to be a solution developed because of the nature of the problem.

In order to unlock the radio, you first need to unlock the boot loader so that you can flash the China Retail recovery and radio which allows open GSM service.

Unlocking the boot loader has, thus far, proven to be impossible on these models.

    TBH Band Config Unlock zip Install for Razr

    It's not "Magic code".

    It is just a zip installation of the NVM edit using the updater-binary from an official OTA update.zip to write the 8 byte string for the band config to NV Item 1877.

    The NVM is updated every time you get an OTA in order to increment the version numbers and dates. We just used the binary for our own needs.

    So far, we have not had complete success with this on the D4 or Razr on stock hardware with T Mobile or ATT in the US. There appears to be a different form of lock in effect for domestic GSM carriers, because there are many reports of it working with international carriers, at least on D4.

    There is a Chinese engineering ICS build that P3droid has running on his eng Razr and everything works out of the box with that radio image. It cannot be loaded on stock hardware unfortunately.
    We dumped the entire NVM from it and I have been going through it to find a potential solution. There are many differences in the NVM and it will take some time to work through them to determine their impact.

    Edit: I have included the Razr version of the TBH band config zip files for those interested in testing this.

    These files MUST be run from Razr bootstrap recovery and NOT Safestrap.
    The unlock zip writes the GSM band config string and the relock zip writes the stock string to revert if you need to for any reason.

    They do no other modifications to the device and any build.prop edits or additional apns-conf.xml or system libs must be done manually if desired.

    Please post back with any information regarding success or failure using these files, thanks!
    The files did not upload from my dropbox properly, sorry. I will have to reattach them from PC later.

    Edit 2: I reuploaded the files. These have been tested on mine and P3droid's Razrs and should work fine.
    As people quickly discovered, the D4 files work on the Razr too, so you can use either. The binaries are compatible and the string is the same. The Chinese ICS build has a slightly altered string that you can also try in RadioComm if desired.
    The first 2 bytes are different: 8001E80400000200

    ***UPDATE 6/26/2012***

    Ok, not all the info that I got before was 100% correct. It looks like RAZR / MAXX is unlocked only for Global(GSM) use which is outside of USA. The Tmobile and ATT sims are not fully working as of right now.

    We have couple amazing Devs which are working to resolve this issue.

    Please PM me if you want me to update the OP.

    -----------------------------------------------------------------------------

    On the Bionic forum people found a way to activate disabled feature of couple 4g verizon phones to be able to use it on GSM networks.

    Can someone test it please?

    ***UPDATE***

    Follow this steps to make it work: http://forum.xda-developers.com/showpost.php?p=25967009&postcount=118

    how did you do it , as in the steps and the carrier you used, att or tmo.
    assuming it's att as you are on 850 3g, also can you please post a pic for us.
    we will be so happy :)

    Actually its pretty easy , no need of Radio Comm

    I have a Moto CDMA XT912

    Steps :

    [optional] Flash this : ICS ROM > http://bit.ly/JW8j8w
    [optional] Flash this : GAPPS > http://bit.ly/JW7vAG

    Flash this : GSM PATCH > http://bit.ly/JW7Hjd
    FLash this : "MAGIC code" lol > http://forum.xda-developers.com/attachment.php?attachmentid=1048524&d=1336485537

    Reboot , and done ! , you'll have GSM enabled [ all bands ]

    I am not giving up anyone. Right now still working on unlock for xt912 for my wife since she hates changing phones. Can't ask for anything better then a phone that can do both CDMA and gsm. We are planning a trip to Asia after the baby is born.

    From what I've gone through so far I can't seem to find anything in particular in any of the nv items that jumps out. I've tried comparative with a SIM card, without, all kinds of ways. Something that was brought to my attention is that even though this phone has the same radio chip, it has a seperate Lte on chip that the other razr's don't. I've found where in the bp.img the us frequencies are blocked. But it's not as simple as overwriting or rewriting the values as that still breaks the signature on the expected filesize check. I also found a value table when going through the mmcblk1 pull and I'm going to see if I can use that to manipulate the bp.img file. Who knows. Just finished my school reports so I got some free time tonight and tomorrow night. Anyone who's up late can through me a google+ chat "queberican351"

    Oh, and the bp.img does reference 0F as a trigger for the 255 (Network ID) and 65535 (System ID) block. Maybe that's somewhere to start. But there are ALOT of locations in the NV dumps containing 0F

    This is the values table I found. I don't know that it'll help us but anyone who knows a lil sum'n sum'n to do with this here you go.

    0 = NULL
    1 = 38.4
    2 = 76.8
    3 = 153.6
    4 = 307.2 short
    5 = 307.2 long
    6 = 614.4 short
    7 = 614.4 long
    8 = 921.6
    9 = 1228.8 short
    A = 1228.8 long
    B = 1843.2
    C = 2457.6
    D = 1536.0
    E = 3072.0
    F = VarRateNonOverride
    10 = 460.8
    11 = 614.4 (4slot)
    12 = 768.0
    13 = 921.6 (4slot)
    14 = 1075.2
    15 = 1228.8 (4slot)
    16 = 1843.2 (2slot)
    17 = 2150.4
    18 = 2457.6 (2slot)
    19 = 3686.4
    1A = 4300.8
    1B = 4915.2

    I also found that NV_ITEM_8044 listed Unknown acts as an NV-READ_COUNTER
    Every time I read it's value the 2nd byte goes up 01,02,03 progressively.
